The AUCHAN Group opens its first HQE-certified warehouse in Trappes

The keys to successful project completion include:- All pollution from the former site has been cleaned and asbestos removed; 97% of the building materials used (wood, glass, steel) were recovered from demolition sites and reused.- Installation of a green roof system (covering 520 m2) above the building's utility rooms in order to improve heat exchange.- Creation of 2,880 m2 of natural lighting, equivalent to 6% additional overhead light, thanks to skylights (3 times greater than the regulatory requirement, set at 2%). A white interior paint better reflects the natural light, inclusion of motion detectors with illumination settings.- BBC©-certified building that yields energy savings of 55% electricity and 25% gas, compared to the former facility.- Water management features: partial recovery of rainwater from the roof for watering the site's landscaped areas, cleaning the ground and supplying toilets (tank capacity: 80 m3, annual recovery objective: 900 m3). Flow rate reducers installed on faucets, men's lavatories equipped with a waterless system.- Installation of solar thermal panels (covering 47.4 m2) to heat water supplying the showers and lavatories.- Implementation of a Technical Building Management system for the purpose of optimizing electricity, gas and water consumption inside the warehouse.- Waste management practices: sorting of recyclables in dedicated bins depending on existing waste streams. Each employee has been trained in the sorting protocol.- Ledger strips raised 20 to 50 cm off the ground, thus facilitating package handling and reducing the need to bend. Employees were closely involved in this project: multiple information sessions to better understand the Sustainable Development approach and best practices, group workouts with musical accompaniment to adapt to the new workstations, and an in-house contest organized to come up with the name of the new warehouse: "ECO-TRAPPES".
